FISHING-TOOL FOR SUQKER-HODS OR THE LIKE.

SPECIFICATION formingpart of Letters Patent No. 759,454, dated May 10,1904. Application filed September 30, 1903. Serial No. 175,170. (Nomodel.)

To all whom it may concern:

Be it known that we, OMAR A. MANN and WILLIAM J. EVANS, citizens of theUnited States, residing at Oil Center, in the county of Kern and Stateof California, have invented new and useful Improvements in Fishing-Tools for Sucker-Rods or the Like, of which the following is aspecification.

Our invention relates to improvements in means for recovering andremoving broken sucker-rods or other and similar obstructions fromoil-wells.

It consists of the parts and the construction and combination of partshereinafter more fully described, having reference to the accompanyingdrawings, in which- Figure 1 is a vertical central section of well,showing our invention. Fig. 2 is a vertical central section of ringportion. Fig. 3 is a bottom view of same. Fig. A is a top view of same,showing latch. Fig. 5 is a section of coupling.

A represents a well-tubing in which operates the usual sucker-rod 2,comprised of a series of separable sections united by suitable couplings3.

Not infrequently in deep-well pumping the rod breaks or becomesdisconnected, whereupon it is necessary to fish out from the bottom ofthe well the remnant of the rod be-.

fore operations may be resumed.

The object of our invention has been to design a simple durable devicewhich may be lowered into the well, slipped over the end of the brokenrod, and engaged with a coupling or like protuberant part on the rod andthe latter, with its bucket, drawn upward to the surface. This devicecomprises a hollow cylindrical section 4 of slightly less exterior diameter than the interior diameter of the welltubing, so as to be freelyreciprocable therein, at the same time not to allow a rod or other toolwhich is to be recovered to pass between the cylinder and the tubing.

The section is provided with the bail 5, consisting of a suitable numberof rods, preferably three, terminating at the top in a union 6, by whichthe device may be attached to an operating-rod and connected to thesection so as to leave suflicient space for the hinging and propermovement of a bifurcated catch or clutch member 7 This catch is pivotedon one side of the top of the section and is adapted normally to bridgeover and rest on the end of the section.

The inner sides of the catch are parallel, and the width of theintervening space 8 is in excess of the diameter of a sucker-rod, butless than the diameter of a coupling 3, since the device is adapted tobe lowered over a rod, the rod passing up through the cylinder andbetween the arms of the catch, lifting the latter to allow it to passbelow a coupling. When the device is lifted, the catch engages beneaththe coupling, and the rod is lifted to the surface.

The bottom edge of the cylinder is beveled, as at 9, so that ordinarilyin lowering the device and engaging a broken rod, which usually leansagainst the tubing, the rod will be fed into and through the cylinder.However, in order always to insure the engagement of the rod by thedevice the cylinder is provided with a notch 10, having a vertical wallportion 11, beveled outwardly to form a sharp edge which will cooperatewith the tubing when the device is turned in the right direction onstriking the top of a rod to draw the rod into a cylinder. The device isthen lowered over the rod, the latch lifting to permit it to ride over acoupling and then'dropping back on top of the section and straddling therod. On the device being drawn out of the well the broken rod is carriedwith it. In engaging the rod through the agency of notch 10 and wall 11any suitable means may be employed to rotate the deviceas, for example,a pipe-wrench, as shown at 12, gripped to the operating-rod 13,carrying-cylinder 4, and turned by hand.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is"- 1. A device of the class described comprising asuitable body having a central opening and a hinged bifurcated clutchmember normally resting on the top of said body and bridging saidcentral opening.

2. A device of the class described comprising a hollow cylindricalsection, means for connecting it to an operating-rod, and a slottedplate hinged to one side of the section and normall y bridging theopening therein.

3. A device of the class described comprising a hollow cylindricalsection, and clutch mechanism carried by said section, and comprisingapivoted bifurcated member normally resting on top of the section andacross the central opening thereof said section having a beveled part tocooperate with the tubing to engage and direct the rod or otherobstruction which is to be recovered into the section.

4. A device of the class described comprising a hollow rotatablecylindrical section and clutch mechanism carried thereby, said sec- 5tion having a notch in its under side and said notch having a verticalbeveled Wall adapted to cooperate with the Well-tubing.

In testimony whereof We have hereunto set our hands in presence of twosubscribing wit- 2
